Forget about ISIS for just one moment: The deadliest terror group in the world now might be Boko Haram.

A report released Wednesday by the Institute of Economics & Peace said the African Islamic group slaughtered more people last year than any terror group in the world — even ISIS, which Boko Haram has pledged to follow.

Boko Haram — which is based in Nigeria with cells in Cameroon, Chad and Niger — murdered 6,664 people in 2014, compared to 6,073 deaths at the hands of ISIS, the report says.

That stunning death toll is a 300% jump from Boko Haram's fatality count from the year before. Most of the evil group's attacks are focused on Nigerian civilians in public, "most often with firearms resulting in very high levels of deaths per attack," the report said.

Boko Haram claimed several attacks through 2014 that each left hundreds dead, including an attack on the city of Gamboru Ngala that killed 315 people.

The world's worst terror group pledged allegiance to ISIS earlier this year, calling itself the Islamic State's West Africa Province, and even uses the same black-and-white flag as the Syrian terror group. But reports of Boko Haram horrors are usually less prominent worldwide than ISIS attacks, thanks to Boko's apparent absence from Western nations.

Put together, Boko Haram and ISIS are responsible for half of all terrorism-related deaths worldwide, according to the report. ISIS claimed the deadliest attack of 2014: An October prison raid in Badush, Iraq, which ended with the slaughter of 670 Shiite captives.

The report also names the Taliban, Fulani militants and Al-Shabaab among the most deadly terror groups active now.
